Harley, I am expecting more than a subtle change with the Pass. I took home a $3K Van Alstine 600R Hybrid tube amp to review for Mr. Van Alstine and the step up in sound was huge compared to the A21. If the difference between the Pass and the A21 is subtle, then I will sell the Pass and probably buy a used ARC tube amp or even a used pair of the Nuforce Model 9se version 2 monoblocks.

As far a music, I am not really looking for suggestions as much as looking at what other people like which in turn may turn me on to new music and stimulate some conversation on this forum.

I have several XRCD's, Blue Coast Music, Cowboy Junkies, Vocalists, Jazz and a couple of Telarc Classical music samplers that I like for their pristine recordings.

Unfortunately, I am in a Las Vegas for a medical conference and won't be home when the Pass amp arrives. I get back home on wed. night.
